This vinvention relates to improvements in record binders, and refers more particularly to binders for loosele'af records; such as Federal, State, county or municipal records. 1

The salient features of novelty residein fthe construction of the backbone orrigid support which vextends longitudinally of the rear edge of the sheets to be bound, and the vmanner in which this support or backbone is attached to the covers or sides of `the Lbinder by channel membersrigidly held in an uprightposition upon the inner face of the backbone.

`Herctofore it has been conventional practice to `form the backbone of a substantially semicylindrical piece of metal, or of relatively rigid ber board,or other suitable resistant material. The channellmembers and post assemblies which support' the loose leaf sheets and fasten the sides.`

Y The lower :portion of the View hasthe sheets Arewhen hinged to the edges of a backbone `of `this type, produce difficulties in properly aligning the posts and channels when the record sheets are inserted orremoved from the binder.

Another advantage of theuse of asolid backbone is thefact that the ridges or hubs on the outercurved surfaces conventional to Athis type binder may be formed on the backbones by turning, thus reducinglabor and expense now required to apply separate pieces to form the hubs. Upon thel inner faceor iiat surface of the backboneare parallel grooves which receive en. gaging members or slides which hold the chan?, nels to the backbone, and accuratelyspace the channels apart so that the bridging posts which hold` the record` sheets fall readily in position andare easily engaged by the pintle slides which hinge the posts and sides to the channels. Wedge members or dowels inserted in the ends of the grooves prevent the channel slides from being displaced longitudinally.

Pintle slides which hold the ends of the posts to the channels and hinge the sides to the channels are so designed that in one position they permit removal of the record sheets by releasingv the posts while remaining in engagement with the hinges, and in a second position engage both the hinges of the covers and the ends of the posts.

In the accompanying drawing, which forms part of the instant specification and is to be read in conjunction therewith, and in which like reference numerals are used to indicate like parts in the various views,

Fig. l is a side elevational View of the binder moved to expose the grooves in the backbone,

Fig. 3 Fig. l, in the direction of the arrows,

Fig. i is a view taken along the line 4-4 of Fig. l, in the direction of the arrows. The binder vconsists of a backbone l which has an outer curved surface, andan inner relatively iiat surface. On the curved outer surface are usually formed a plurality 0f ridges la., known` in the art as hubs. The backbone here shown is of wood and the hubs formed on the curvedy the shapeof a dovetail, as showninlcross-section in Figs. 3 and .4.` Positioned upright upon 1 `the flat inner surface of the backbone are channel members 2 which have a hollow body, and plates 2a which lie nat againstl the surface of the backbone. Extensions of the plates 2a. are formed` as angle slides 2h, whicht the contour of thev longitudinal'grooves inthe backbone and hold the channels 2 in an uprightposition at right angles tothe flat inner surface of the backbone.` Whiletlie grooves in the backbone are dovetailed in shape, and the angle slides 2b are formed to nt. these grooves, it should be understood that this particular shape which has beenchosen forthe grooves is notarbitrary, but

may be' varied as long as the channels are held rigidly at right angles to the backbone. Furthermore, it is desirable that the width of the groove at the surface of the backbone be somewhat less than the width at the bottom of the groove, thus preventing outward displacement of the slides from the grooves, that is, requiring the removal of the channels from the backbone by sliding the channels lengthwise of the backbone until the slide passes entirely out ofthe groove.

To hold the channels in place on the backbone and to prevent longitudinal displacement of the slides inthe grooves, dowels or wedges 3 arel Within the hollow body portion of the channelsl is a view taken along the line 3--3` of` 2 are pintle slides 4, which have a plurality pintle extensions, two of which are relatively long and designated as 4a, and four of which are shorter in length and designated as 4b.

The top edges of the channels are cut away at predetermined locations, as shown at 2c, to accommodate the eyelet ends of hinges 5 bymeans of which the covers or sides 6 of the binder are attached to the channel, and also to receive eyelets in the ends l`of .postsjl which hold therecord sheets. Y K' v The hinges '5 may be formed of strips of a suit-- able material, such as metal, plastic or liber.. Fiber is now being used in place of metal due to War conditions. The ends of the hinges areiembedded in the cover between the layersofn plywood and pressed wood which form the material of the cover, and are held in position .in they plysides and the backbone, are usually covered by suitable flexible materih such as leather, buck` channels throughout the length of the backbone, thus facilitating assembly and ease in removing and inserting the posts when record sheets are inserted or removed from the binder. It has been found that the abutment of the posts on the edges of the sides holds the record sheets in place while the opposite ends of the posts are fastened in the channels at the opposite side of the binder.

Figom,the,foregoing it 1will .beseen that the invention fisLonevvell adapted to attain all of the ends and objects hereinbefore set forth, together with other advantages which are obvious and which are inherent to the structure of the device.

The manufacture of the backbone is relatively simple. Wood, usually ,magnolia' which is rela,- tively light andtoughand has a grain somewhat similar to maple, is cut with a flat side. and av curved side, and after v'grooving the separate pieces aremounted upon a mandrel and. the

hubs la turned ony the curved surfaces.V The.

channels are formed of lightmetal. strips inrelatively simple vforming operations. `'I'he manufacture of the sides and. pintlesis conventional except that V'the design of the pintles `is unique in thatit permits posts whichlholdthe record. sheets to be-.released on` one or both sides in order thatv the. recordsheets maybe removed without dis-1j turbing the covers or sides of the binder.

It is evident that the manner of attaching the channels rto the backbone besides providing a rigidlstructur'e, accurately spaces the baokedges ofthe sheets fromv the backbone and .maintains a definite spacing of vthe channels so that the posts. can be readily lassembled or removed when inserting :record sheets. or yremovingV record sheets from the binder.4`

.The angle slides ofthe 'channels with-*the grooves ofthe backbone provide a rigid assemblfyTv ofthe binder and'eliminate tedious, expensive riveting'or screwingcperations heretofore neces'- sary in attaching channels tothe binder.

The dowelsfor wedges whichhold the slides-in place besides serving this functioniill thegroovesA and renderthe backbone more rigid. Thegroove and slide arrangementfor attaching the channels also, positively controls the' spacing between the hinged, to .the edges.` of the therefore, ,to beunderstood Athatmy invention is not to be limited to thespecic detailsshownr anddescribed.v
